W ARNING

1. Remove shipping t ape(s) and pack ing as fol lows . If any left i n the icem aker ,
it will not w ork proper ly .

2. Do not lift or carry t he unpacked ic emaker by us ing the bra ss fitting for water
supply at the r ear of the unit. The plasti c threads may be damaged.

IMPORTANT

1. Remove the shipping tapes holding the Door and Separator.

2. Ensure all components, fasteners an d thumbscr ews are securely in pl ace.

* Remove the package containing accessories.
* Check that refrig erant lines do n ot rub or touch li nes or other sur faces.

2. LOCATION

W ARNING

This icemaker is not intended for outdoor use. Normal operating ambient
temperature should be within 50°F (10°C) to 100°F (38°C); Normal operating
water temp er a t ure should be within 41°F (5°C) to 90°F (32 °C). Operation of
the icemaker , for extended periods, outside of these normal temperature ranges
may affect production capaci ty .

For best operating results:
* The icemaker should not be located next to ovens, grills or other high heat producing

equipment.

* The location should provi de a firm foundation for the equipment. Lev el the i cemaker from

side to side and front to rear.
* Avoid a site w here drippi ng i s not allow ed.
* This icemaker will not work at subfreezing temperatures. To prevent damage to the water

supply line, drai n the icemaker when ai r temperature is below zero.
* The AM-100BAE icemaker requires no clearance at either side. But allow enough space

at rear for water supply and drain connections, at least 12” (approx. 30 cm) clearance at

front, and at least 0.6” (approx . 15 mm) cleara nce at top for main tenance.
* The AM-150BAF icemaker r equires 2” (approx . 5 cm) clearance at either side. Allow enoug h

space at rear for water supply and drain connections, at least 12” (approx. 30 cm) clearance

at front, and at least 0.6” (a pprox. 15 mm) cle arance at top for mai ntenance.

3. SET UP
IMPORTANT

Do not place heavy objects exceeding 33 l bs (15 kg) on the Top Panel.

1) Unpack the icemaker, and remove all shipping cartons, tapes
and packing BEFORE operating the unit.

2) Position the i cemaker in a selected site. Clean the interior
with soap and w ater and rin se thoroughl y .

3) Level the ic emake r in bo th the l eft- to- r ig ht an d t he fr ont- t o­rear directions (when installed with or without legs). See Fig.

2.

4) When installing the unit without legs, the perimeter where the
machine touches the counter shoul d be sealed wi th silicone
to prevent wate r from leaking under the icemak er .

Max. 0.4” (1 c m)

T apped Hole
(Leg Mounting)

5) When installin g the unit with legs on the botto m, use the four
accessory legs adjustable from 6” (15.2 cm) to 7” (17.8 cm).
Screw the legs tightly i nto the tapped holes in th e base (see
Fig. 3). Handle the icemaker carefully not to damage the
exterior.

4. ELECTRICAL CONNECTIONS

W ARNING

THIS APPLIANCE MUST BE GROUNDED.

This icemaker requires a ground that meets the national and local electrical
code requirements. To prevent possib le severe electrical shock injury to
individuals or extensive damage to eq uipment, install a proper ground w ire to
this icemaker . Remove the plug from the mains socket before any maintenance,
repairs or cleaning is undertaken.

* This icemaker must be plug g ed i nto the separated power receptacle which has eno ugh

capacity. The maximum allow able vol tage v ariation should not exceed ± 10 percent of the
nameplate rating. See the Namepl ate.

* Usually an electrical permit and serv ices of a licensed electrician ar e required.

6

5. WATE R SUPPLY AND DRAIN CONNECTIONS

W ARNING

To prevent damage to the freezer mechanism, do not operate this icemaker
when the w ater suppl y is OF F, or if the pr essure is below 10 PSIG (0. 7 bar), the
recommended water pressure. St op the icemaker until pr oper water pr essure
is resumed.

CAUTION

1. A brass fitting for the water supply line connection is attached to the 3/4” BSP
plastic threads to avoid cross-threading of the Water Valve possibly resulting
in leaks. The brass fitting allows connection of a 1/2” FPT that should be
connected to the potable w ater supply lin e.

2. While making the water supply line connection, use a wrench to hold the
brass fitting still to prevent overtightening and damage to the plastic threads.

* Water supply inlet for the i cemaker is 1/2” female pipe t hread (FPT).

Note: On water-cooled model, two water supply inlets are pro vided. One is for the i cemaker

(1/2” FPT), and the other is for the water -cooled condenser (1/2” FPT).

* The brass fitting is attached as shown in Fig. 4. The fitting size is a 1/2” FPT and must be

connected only to a pot able water supply.
* A water supply line shut-off valve and drain valve must be installed.
* Water supply pressure should be a mini mum of 10 PSIG (0.7 bar) and a maximum of 113

PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), use a pressure reducing valve.
* Drain outlet for icemaker dump is 3/4” FPT.

Note: On water-cooled model, a 3/8” FPT is pr ovided for the con denser drain outlet. The

icemaker drain and the condenser drai n piping connecti ons must be made separate ly .
* Drain must be 1/4” fall per foot (2 cm fall per meter) on horiz ontal run s to get good flow.
* Keep a more than 2 vertical inch (5 vertical cm) air gap between the drain pipe end and the

sink.

* The drain pipe must be so laid as to prevent a backflow into the Storage Bin. Provide a trap

in the bin drain li ne to prev ent odor from flowi ng back into the S tor age Bin.

7

* A plumbing permit and services of a licensed plumber may be required in some areas.
* This icemaker should be installed in accordance with applicable national, state and local

regulations.

2. MAINTENANCE

IMPORTANT

This icemaker must be maintained indi vidually , referring to the instruction manual
and labels provided wi th the icemaker .

1) Exterior

To keep the exte rior cl ean, wi pe occasiona lly w ith a cl ean and soft cloth. U se a damp
cloth containing a neut ral cleaner t o wipe off all oil or dirt buil d-up.

2) Air F ilt er

A pla stic mesh air fil ter remov es di rt or dust from the air, and keeps the Condenser
from getting clogged. As the filter gets clogged, the icemaker’s performance will be
reduced. Check the filter at least twice a month. When clogged, use warm water and
a neutral cleaner to wash the filter.

3) Condenser

Check the Condenser once a year, and clean if required by us ing a brush or v acuum
cleaner. More frequent cleaning may be required dependi n g on the location of the
icemaker.
